Abstract

PCT No. PCT/FR85/00163 Sec. 371 Date Jul. 22, 1986 Sec. 102(e) Date Jul. 22, 1986 PCT Filed Jun. 19, 1985 PCT Pub. No. WO86/03142 PCT Pub. Date Jun. 5, 1986.Improvement to the separation and recovery of solids from liqiuds containing them, and using a ionic flotation process, implementing an installation characterized in that it comprises at least a vat (1) for pretreating the solution to be treated for the insolubilization of the solid to be recovered and the formation of a suspension maintained under stirring conditions (stirrer 2), at least a flotation cell (5) supplied with said suspension, at least a device (4) provided between said vat (1) and said flotation cell (5) adapted to generate within the cell a rising non-turbulent stream intended to convey the desired solid towards the surface of said suspension while maintaining at said surface a calm area for the accumulation of said solid and at least one means for the recovery of said solid (6-7).
